Truth Hardware Replacement Part
Thanks for reaching out to us! The window operator you have here is the 39-031 EntryGard Dual Arm Operator. To confirm that this is the right replacement, carefully look over the dimensions.
I've tagged the opposite version of this operator and all of the compatible hardware and accessories below for your review.
I see here that your diagram includes that looks like the dimensions for the casement hinge. If you are looking to replace it, I suggest taking a look at the 36-048 2-Bar Hinge Set. This can be used to replace the top and bottom hinge for left and right handle applications.
It is advised to replace both the top and bottom hinge to ensure they will be a match.
Great to hear! We are happy that we could assist with your repairs and please let us know if you have any future hardware questions!
